Hey Cozer, what are some of the Zoas names in your "Puzzle" ? I was having a tough time finding them on CoralPedia.

Actually, I didn't search for the names of those zoas! But I suggest you to do the search work on the website below:

CoralPedia.com! :: The definitive repository for named Corals!

Here you can definitely find almost every species of zoas commertially available!

Hey David, I am in a project that I wish to finish and setup before this year ends for propagation of corals using natural light and I notice that your tanks have a chamber to the left side. How does this chamber works? Is it like an overflow in the same tank?

[SECRETREEF]

I am also going to use suplementary led lighting to save energy and to see them when the sun goes down.

Did you mean the left part of the tank shown below?


That is a reservoir for the fresh water being added! The plumbing is connected to the sump. Any deviation on water level can start the addition of fresh water from this reservoir!

Looking forward to the fixture you will use for the supplemetary lighting!

how long have you been using your led? have you seen your corals grow with led? I am asking for your help because I need to know what type of investment I'm getting into. great tanks and corals keep up your good work!

I've been using the LEDs for two months on the 20 gal "Zoa only tank" and one month on my 50 gal display! In the case of the 20 gal, the zoas show great coloration especially under the illumination of blue light, and some species seem growing in number and some don't! As for the 50 gal display, similar condition can be observed but one thing I've noticed is that all of my SPS show more apparent growth sites on their top ends than before. However, one-month use is still too short to give a conclusion for your question! Wait for my coming update events!

[SECRETREEF]

great I will wait for your results since this is going to be a project that will take long to finish I think a few more month and the light will be one of the last things I am going to buy. thanks a lot i'll be keeping in touch

I just had a chance to go throught the whole thread, nice tank. Colors are very interesting.

Hey cozer mind seeing how my zoo's are doing i got 4 compare pics from MH/actinic and LED.
How long did it tank for your zoo's to color up? Ive had mine under leds for about a week maybe a day or to more jsut wondering, im not in a rush or anything jsut wanting to see a cmoparison between urs mine and my old MH pics.
Its not gunna be entirely accurate b/c were using different led systems, but the ideas there.

MH/Actinic-had them for about 2 weeks

LED-under led for about 9 days

MH/actinic- theres were in tank for like 3 months

LED - 9days after change


man i wish i could get my camera to take close ups better, this really doesnt do anything justice

[cozer]

Hi migget!
I just take a view of the four pics. Before giving you any suggestion, I would like to know what is the spectation of the LEDs you use as the light source? The wavelengh? The power consumption per LED? Are there any blue LED in the fixture? What is the ratio of white/blue LEDs? In my case, the ratio is about 1:1, and I am still not totally satisfied with the coloration of the zoas under this light. My observation is that the intensity of the light is not the only factor but the "quality" seems to affect more! I recommend you to read two articles talking about the influence of light spectum on the coloration of corals. The two interesting articles can be connected below:

Advanced Aquarist's Online Magazine - Feature Article: How to Make Corals Colorful, Part One: New Information, With Particular Attention to Blue-Green Fluorescent Pigments

Advanced Aquarist's Online Magazine - Feature Article: How to Make Corals More Colorful, Part Two: New Information! Green Fluorescent Pigments, Pigment Clades, and Photoconversion from Green to Orange/Red

[migget]

Well some of the info im goling to have to call him on. Ill be getting back to this thread with as much info as i can about the wavelenght, power consumption, ratio, etc.

The tubes on my 65 gal are as folllows. Im using 2 different kelvin of led, 12k and 16k along with 440nm or blue leds, and a tube mixed 1/3 blue w/ 2/3 red led.
252 pcs per tube
lum flux- is 1638Lm
PC- 15w per tube
TC- 440nm
forward voltage- ac85c-ac115v

Ill post more on the things you ask when i can get them. I know persoanlly since ive added the leds on both tank tht everything seems to be out more, the polyps are out more, the zoo's are opened up more the xenia seems like its standing up more and pulsing more. I dont know if b/c it needs more light or its b/c it likes what it has. NOthing in either tank looks like its going down hill so far but like i said its only been about 9 days for the 65gal and 4 for the 120gal. Everything jsut "SEEMS" happier but tht doesnt mean tht its gettign the proper amount of light.

I know tht my fish are freaking lovin it. They swim all over the tank not just hiding in the caves and near rocks. My tangs swim everywhere not jsut on the glass but all over top to bottom. Everything jsut seems like it lieks it better i dont know, ill be able to tell more as time goes and i know it doesnt show it but the colors of everything seem to more true. Granted thigns will have to adjust but still. Heres a link to the wevsite were i got the bulbs/tubes from i hope this may help a lil more.

Did you get my PM?

Hey David, its been awhile since I have chimed in this thread haha. How are the LEDs running on your 20g and 50g?? Any comparisons or noticeable improvement with the Zoanthids?

I just upgraded my LED fixture for my 20 gal "Zoa Only" last week. I added two more blue LED sets and two moonlight modules in the fixture for test. Here are some pics of the tank and the fixture after the changes:

What do you think of it? Any big difference can be clearly pointed out?

[migget]

I do see a difference in color intensety. The more blue ive seen you have in the a tank the more color your gunna bring out of whatever your lighting, and the white is basically just for growth. Your not gunna get more color from it, some but not much.
Cozer i recently moved most of my zoa frags to my 120gal which has more blue and red lighting, jsut basically more verisation in lighint spectrum and there is a huge difference in color.
The more blue spectrum at least with LEDs the more color your gunna get and man esp. the zoa's grab the color and hold it and color up fast. I was running 1 blue tube, 1 red , 2 12k and 2 16k and it was jsut to daylight color if you could say, there was still color but not near as much as in with more blue/red spectrum im gettign with the 22's and blue/red, and blue tubes ive got in the 120.
I see the same thing with your tanks. Your using the white basically for growth and and nutrients and the blues and reds for color and the more you add the more vibrent the coloration your getting. I hope you've noticed the same thing.

First, I have to say that the light intensity did increase a lot after adding the two more blue LED sets. One may not see the difference on light intensity due to the camera setting and the post-treatment of photos. Yes, I agree with your observation of the coloration enhancement under the blue/red spectrum.

If you have read the two articles in the journal of "Advanced aquarium" talking about the influence of lighting spectrum on the coloration of corals, you should also know that the color we can observe by naked eyes is actually excited from certain proteins in the corals after absorbing a shorter wavelength light. Most of the proteins seem to prefer the light with short wavelength (like UV or blue light which provides higher energy), and then excited light with longer wavelength (like orange or red light).

The white LEDs although provide full-spectrum of light, but LEDs with certain colors provide even higher quantity of certain light spectrum under the same power consumption. This means that one can enhance the coloration by using solely narrow-ranged spectrum LEDs, such as blue, green or red ones just depend on what kind of spectrum do the coral need most for the excitation!

In my opinion, I don't use only blue and/or white LEDs but also red ones. The addition of red light is signicantly efficient on the performance of most fishes since their colors that we observed are mainly due to the direct reflection of light illuminated on them but not a absorption-exitation process!

Hope this would help to anyone who are also curious about the influence of LED lights on marine tanks!

I argee, i had been typing in a thread were the guys used jsut actinic lghting in his 29gal bio-cube and his zoa's took off tripling in growth and color and size. His acros didnt like it as much also his lps, but i thin ktht was due to the way the absorbe the calc out of the water to grow. There is something in there system tht needs tht intense light jsut for growth alone, then you add the actinics. All this is starting to make sense to me since you see most of the more colorful acros, zoa's and lps in the deeper regens of the ocean. As long as tht growth protein is stimulated to grow the coral will be fine, but the deeper u go the more blue the water being, hence the more blue lighting or spectrum will simualte tht environment. If im correct then the shallower water coral would thrive with the white light b/c thts all their used to.
Plz tell me if my observation is wrong or if you agree?

The LED lighting fixtures:

Moonlight modules ON


Moonlight + Red modules + 4 Blue sets ON

Wow, added a whole bunch more I see, looks awesome (and much brighter too.) Does the additional red LEDs aid in the "color pop" of the Zoas? That section of the spectrum is supposedly all you need for the reds, oranges and yellows to become more vibrant. A good bulb combination is key for great color rendition, you certainly have all that is needed. I bet seeing it in person would be a lot different, just like seeing The Grand Canyon, pictures just don't do a justice lol, correct?
